PE Sheet Extrusion Line

The PE Sheet Extrusion Line is designed by Jwell for stable production of medium to thick sheets. The product thickness range is 3–30 mm, sheet width can reach 1220–2000 mm, and the output capacity is approximately 500 kg/h. It is widely used in packaging, construction, automotive interiors, and industrial protection. Common products include PE protective sheets, chemically resistant liners, thermoforming substrates, and various structural sheets for engineering applications.

Application

This PE Sheet Extrusion Line produces PE sheets widely used in industries requiring durable, chemical-resistant, and lightweight panels.
Case 1: Storage Tanks for Agriculture & Construction
A Dutch customer uses 15 mm thick HDPE sheet (2000 mm wide) to manufacture chemical storage tanks. The sheet offers excellent UV resistance and weldability, replacing stainless steel at 40% lower cost than stainless steel.
Case 2: Truck Liner & Floor Protection Panels
An Australian logistics company replaced their trailer floors from plywood to 10 mm recycled PE sheet. The JW180-2000 line produces 3000 mm wide seamless sheets, reducing water damage and extending service life by more than 5 years.
Case 3: Industrial Thermoforming
A Polish packaging manufacturer uses 3–8 mm PE/ABS sheets to produce vacuum-formed trays and automotive interior parts. The line’s precise thickness control of ±0.2 mm ensures consistency in forming results.

Advantages

High Output & Energy Saving
500–800 kg/h continuous production, low melt temperature design → approximately 15% energy saving compared to conventional single-screw extruders.
For PE material, we use a special barrier screw to increase plasticizing capacity without increasing screw length.
Wide Width & Thickness Flexibility
Quick change of dies from 1220 mm to 3000 mm. The JW180-2000 handles 3–30 mm thickness and is equipped with hydraulic die lip adjustment – no manual shims required.
Multi-Material Capability
Process virgin or recycled PE (HDPE, LDPE, LLDPE), PP, and ABS on the same line. A quick screen changer and purge system reduce material changeover time to within 2 hours.
Robust Construction
Forced lubrication gearbox and hardened barrel – designed for 24/7 continuous operation. A real user from Turkey reported that after heavy-duty use for 8 years, the screw has not yet been replaced.

Process

We test each extrusion line before shipment according to a 7-step QC process, ensuring compliance with CE and ISO standards.

Step	Inspection Item	Equipment/Method
1. Raw Material Verification	Check MFI and moisture content	Lab melt flow indexer, moisture analyzer
2. Barrel & Screw Inspection	Water circulation test, screw concentricity	Dial gauge, thermal imager
3. Die Lip Calibration	Measure full-width flatness (tolerance ≤0.05 mm)	Laser micrometer, feeler gauge
4. Sheet Thickness Monitoring	Online ultrasonic or beta gauge, 6-point full-width scan	NDC or Zumbach scanner
5. Cooling & Pulling Check	Verify roll parallelism and cooling water temperature (20–40°C)	Infrared thermometer, level ruler
6. Winding/Cutting Test	Produce 500 m sample roll, check edge straightness	Visual + tension meter
7. Final Water Trial	Run 8 hours continuously with actual PE/PP material, record output and energy consumption	PLC data recording

Real Quality Assurance Example
For a Mexican customer requiring sheets meeting ASTM D638 tensile strength, we performed online tensile sampling every 2 hours. The 3 mm HDPE sheet produced by the JW150-2000 line achieved 22 MPa – exceeding the customer’s requirement of 18 MPa.

Q1: Can I produce both smooth and textured PE sheets on the same line?
A: Yes. By changing the calender roll surface (mirror, matte, or embossed), different textures can be achieved. The JW series supports two-roll or four-roll configurations – for textured sheets, we recommend a four-roll calender for better texture fixation.

Q2: How to solve thickness variation across 3000 mm width?
A: Our die uses more than 30 thermal expansion bolts (automatic or manual) to fine-tune the die lip gap. In addition, an automatic profile control system (optional) reads online gauge data and adjusts the bolts in real time – keeping variation within ±0.1 mm even at 3000 mm width.

Q3: What is the MOQ for spare parts kits?
A: For each line we provide a standard free spare parts kit (screen packs, heaters, belts, seals). For long-term support, we keep screws, barrels, and gearboxes in stock at our European warehouse (Poland) – most spare parts have a lead time of 3–5 days.

Q4: Can I use 100% post-consumer recycled PE?
A: Yes, but with two considerations:
Install a melt filter (≥40 mesh) to remove contaminants.
Output will be reduced by about 15–20% due to lower bulk density of recycled pellets.
A customer in Finland uses 80% rHDPE + 20% virgin material on a JW180-2000 to produce 25 mm construction sheets at 650 kg/h.

Q5: How long does installation and training take?
A: Two weeks on-site:
Days 1–3: Mechanical installation
Days 4–7: Electrical and PLC commissioning
Days 8–10: Trial run with your material
Days 11–14: Operator training + document handover
We also offer remote assistance via TeamViewer for fine-tuning.

Q6: What is the energy consumption per ton of product?
A: For a 500 kg/h line: approximately 180–200 kWh/ton (including extruder, puller, winder). For an 800 kg/h line: approximately 160–180 kWh/ton – more efficient due to larger motors and better insulation.
